Abstract (data abstract)
CERN-LHC. We report measurements of the production of prompt D0, D*+, D+ and D/s+ mesons in Pb-Pb collisions at the centre-of-mass energy per nucleon pair sqrt(sNN)=5.02 TeV, in the centrality classes 0-10%, 30-50% and 60-80%. The D-meson production yields are measured ad mid-rapidity (|y|<0.5) as a function of transverse momentum (pT). The pT intervals covered in central collisions are: 1<pT<50 GeV/c for D0, 2<pT<50 GeV/c for D+, 3<pT<50 GeV/c for D*+, and 4<pT<16 GeV/c for D/s+ mesons. THe nuclear modification factors (RAA) for non-strange D mesons (D0, D+, D*+) show minimum values of about 0.2 for pT=6-10 GeV/c in the most central collisions and are compatible within uncertainties with those measured at sqrt(sNN)=2.76 TeV. For D/s+ mesons, the values of RAA are larger than those of non-strange D meosns, but compatible within uncertainties. In central collisions the average RAA of non-strange D mesons is compatible with that of charged particles for pT > 8 GeV/c, while it is larger at lower pT. The nuclear modification factors for strange and non-strange D mesons are also compared to theoretical models with different implementation of in-medium energy loss.
